How to find the longest word in text file?

hello my task is ( given a text file. print longest word of each line.) i have tried seweral ways to do it but i failed.

Code:

void longest_word(FILE *f,FILE *f1)
   {    
          char data[2000];
            int i,len=0,len1=0,k=0;
     for(i=0;i<2000;i++)
     {   
      if(data[i]==EOF) break;
      data[i]=fgetc(f);
      if((data[i]>='a'&&data[i]<='z')||(data[i]>='A'&&data[i]<='Z'))
       {   len++;}
       else if(len>len1)
       {len1=len; k = i-len; len=0;}
      }
  
    for(i=k;i<k+len1;i++)
     fprintf(f1,"%c",data[i]);
	     i++;  
   }

should i use this?


it would be great that someone help me.

The problem is that you are working by characters not words...
Look up the fscanf() function in your C documentation...
For determining the length of words use strlen() on the text from fscanf...

hmm.. i really don't get it wha you say.. could you show me in the program what is wrong? or could you fix the problems becouse my english is very bad

Code seems to be lifted directly from the Internet. Specifically here.

idk what r u talking about?

He busted you for plagiarizing. The sample code you originally posted was exactly the same as the code on the link he posted. But then you edited your post to change the code and claimed innocence. By the way, SMS speak is annoying and further hurts your chance of getting help. You should also only go back to edit a posts for small typos and the like, not for changing big swaths of text, since the following posts won't make much sense otherwise.

Meh, copy/paste artist just found a different example right here at C Board.

If you don't want to actually be a programmer, why did you take a class that requires you to program?

yes i copy paste i just want to know what should i use the best?
